Sulfite Test Kit
Drop-count test kit for sulfite residual in boiler, cooling, and closed-loop water treatment programs.
CI Sulfite Test Kit measures sulfite residual as SO₃ in industrial water systems where sulfite is used to control dissolved oxygen and limit oxygen-driven corrosion. Run on a 25 mL water sample, the test uses drop-count titration to endpoint, with each drop equal to 6 ppm sulfite, giving the operator a direct field check on whether sulfite residual is actually sitting inside the intended treatment range. This is the monitoring side of sulfite-based oxygen scavenger programs: the chemistry removes oxygen, and the test kit confirms enough residual is being maintained to keep protection in place without drifting into blind overfeed. Strong fit for routine boiler, cooling, and closed-loop monitoring where sulfite control is part of the corrosion program.

Operational Notes
• Sulfite is used to control dissolved oxygen; the test kit confirms whether enough residual is being maintained for that oxygen-scavenger program to remain effective
• If sulfite residual falls too low, oxygen-driven corrosion can resume; if it is too high, treatment chemistry may simply be overfed without operational gain
• The test is run on a 25 mL sample, with each drop representing 6 ppm sulfite as SO₃ to endpoint
• This is the monitoring side of sulfite-based treatment: the chemistry removes oxygen, the test kit confirms the residual is actually there
• Best positioned for routine operator checks in boiler, cooling, and closed-loop systems where oxygen control is part of the corrosion program
• Practical field value is simple: verify residual, correct feed, protect the system, and avoid blind dosing
Practical Fit
CI Sulfite Test Kit is the field verification tool for sulfite-based oxygen scavenger programs. It tells the operator whether sulfite residual is actually on target, so feed decisions are based on measured control rather than assumption.
